Work Breakdown Structure (WBS)
Within a project, activities can be grouped, filtered, planned, and organized by Work Breakdown Structure (WBS). The WBS classifies all of the deliverables of a project and is often formed into a hierarchy with an increasing level of detail. How WBS is defined varies by company and by project, but having a well-planned WBS is a key first step to implementing good project controls.
Consider any one of several standardized WBS structures:
UNIFORMAT II Elemental Classification for Building Elements (Publication NISTIR-6389)
UNIFORMAT II Classification for Bridge elements (NIST 1122)
DOT Specs for use in almost every public entity road project. FHWA publication FP-03, also see specific state DOT website for more specific documentation.
FAA Specs for use in every US airport/airfield construction project. FAA Publication AC 150/5370-10.
An example of WBS for a software development project could be:
Needs assessment
Design
Coding
Integration testing
Implementation and rollout...
